There's a repair available in the UK for the Bcsch CP1 HP pump pressure regulator, which contains the O rings and new gasket.

It's definitely a cause for concern. The M47 isn't known to suffer from cooling issues, actually it's known not to suffer them.
Definitely something wrong for coolant hoses to be failing.

Found oil in coolant reservoir and asked the previous owner they say no issues before. A month after investigating, he informed already change major parts in engine causing oil to get into coolant reservoir. But still the same issue after changing the parts.
1. Water Pump.
2.Oil Cooler
3. Crankshaft Pulley.
4. Belting system.
5. Radiator Serviced
6. EGR Cleaning
7. Welding Cooling Pipes.

The garage used a fuel line hose to chnage the radiator hoses. That seems to be the culprit.

When cranking do you hear a regular intermittent lower in speed as each cylinder gets to full compression or does it miss any out? Missed would indicate a drop in compression.

It'll take a lot of time and cleaning to get oil out the cooling system, and that might be responsible for the hoses failing too, as oil will make them soft.
It it's Borneo Indonesia, then 7,000 miles is more accurate. However there's this invention called international shipping.UK is like 2000miles from
where i am
The packet is tiny and very light, so airmail shouldn't be that expensive.

Erm, don't read. Look. Find out where it is coming from.

I am 12,000 miles from the UK and I always buy my parts from the main LR parts suppliers in the UK. It is usually cheaper (even after shipping costs) and they will use the likes of DHL to get the parts to me in a week.UK is like 2000miles from
where i am
I have used Rimmer Bros and LRDirect but I'm sure the others will be just as good.
I have also bought from UK companies listing on eBay - but I'm not sure I would trust and eBay listing or the eBay process. I have googled them and contacted them direct to see if they are able and willing to ship here and seem a reasonable outfit.

true, parts here are ridiculously expensive and they supplier here treat LR owner like a rare item...

Checked the diesel leakage. None found, the residue was water from bursting coolant water and drip near the top section of fuel injector area..

Double check the diesel return leakback, and diesel was overflowing with just cranking through the injection leakback. Try to order from Ebay one but they wont send it to my place for fuel regulator kit

Already check diesel
leakback properly. And there is lots of diesel leakback from opening top fuel rail return. Trying to order the Repair kit for HP fuel regulator kit, but ebay are not sendng it to ly place. Any advice on replacement part or similar item to replace the regulator kit.

I am no TD4 expert - I have the L Series diesel.
However, the TD4 uses a chain driven high pressure pump. If the motor is being turned over, then it will pump fuel.
If the ECU senses a problem, for example the low pressure fuel is not high enough, then it will not fire the engirn - ie it will not open the injectors.
If the pump is pumping fuel and the injectors are not firing, I presume the only place the fuel can go is through the regulator and leak back to the tank.
This scenario there would not necessarily be an issue with the regulator.
However, it could also be that the regulator seals are stuffed, and the fuel is simply being pumped out passed the regulator and not building high pressure.
Normally, I'd have thought you would put diagnostics on the car to see what the high and low pressures are. If they are both within range, then there must be another reason the ECU is not opening the injectors. If the high pressure is not high enough though, it would be very likely that the regulator O ring is shot or the pressure sensor [connector?] is stuffed.
I do not know if that Vauxhall CP1 kit is correct for the pump in the TD4, it looks like it. Others will advise, or if it is local and cheap, worth a go.
